+* Broadcom iProc PCIe controller with the platform bus interface
+
+Required properties:
+- compatible: Must be "brcm,iproc-pcie"
+- reg: base address and length of the PCIe controller I/O register space
+- #interrupt-cells: set to <1>
+- interrupt-map-mask and interrupt-map, standard PCI properties to define the
+ mapping of the PCIe interface to interrupt numbers
+- linux,pci-domain: PCI domain ID. Should be unique for each host controller
+- bus-range: PCI bus numbers covered
+- #address-cells: set to <3>
+- #size-cells: set to <2>
+- device_type: set to "pci"
+- ranges: ranges for the PCI memory and I/O regions
+
+Optional properties:
+- phys: phandle of the PCIe PHY device
+- phy-names: must be "pcie-phy"
+
+Example:
+ pcie0: pcie@...12000 {
+ compatible = "brcm,iproc-pcie";
+ reg = <0x18012000 0x1000>;
+
+ #interrupt-cells = <1>;
+ interrupt-map-mask = <0 0 0 0>;
+ interrupt-map = <0 0 0 0 &gic GIC_SPI 100 IRQ_TYPE_NONE>;
+
+ linux,pci-domain = <0>;
+
+ bus-range = <0x00 0xff>;
+
+ #address-cells = <3>;
+ #size-cells = <2>;
+ device_type = "pci";
+ ranges = <0x81000000 0 0 0x28000000 0 0x00010000
+ 0x82000000 0 0x20000000 0x20000000 0 0x04000000>;
+
+ phys = <&phy 0 5>;
+ phy-names = "pcie-phy";
+ };
